Description

This issue is for the discussion and implementation of data downloads within the Scribe app. As more keyboards are added to Scribe, the size of the app will slowly grow and become cumbersome. To counteract this, it would be best if keyboard data was downloaded by the user in app. Downloading a keyboard would allow a user to then add the given keyboard in the settings.

• This issue blocks #10 as it would be necessary to download the data from a secondary source
